my conspiracy theory is that this game was
always planned to be released in july of this year, and all the delays were to build up hype lol
If the Attribute has to be Data the entire way through, then MasterTyrannomon would not be the evolution. MameTyramon could be
i would also like to mention that sometimes digimon attributes are subject to change depending on the media (like Wormmon is registered as Free in the DRB, but was labeled as a Virus in card games and 02 materials) so its entirely possible for MasterTyrano or even MetalTyrano to be the Data Perfect.
Wormmon's classification as a
Virus was primarily due to
Free-attribute being unavailable and/or inapplicable to that specific media (to be specific, it's inapplicable because such media usually predate the
Free classification; although, the concept of the 'lack of default attribute' of the
02 Digimon existed since the
D-3 toy).
The old TCGs, like
Hyper Colosseum, did not have a
Free classification; thus, Wormmon was classified as a
Virus (or
Vaccine on one occasion). In contrast, any media that did use
Free-attribute would classify Wormmon as such.
This does not apply to MasterTyrannomon. There is no reason why
Survive would exclude
Vaccine but not
Data.
